Question

What is chemical weathering​

Answer 1

Chemical weathering is the erosion/disintegration of rocks, soluble salts, building materials etc., made by chemical reactions.

Answer 2

One of the reasons rocks look so varied in their appearance is because they are subjected to chemical weathering, which is the process by which rocks are broken down by chemical reactions. Different types of chemical weathering and exposure to things such as water, oxygen, carbon dioxide and acids can alter the minerals found in rocks.
